Byte

We explain what a byte is, the origin of the term and what it is for. In addition, some features and their scale of measurements.

A byte needs 8 bits to represent a letter in the binary code.
  1. What is a byte?

It is known as the basic unit of information used in computer science and telecommunications, equivalent to an orderly and regular set of bits (binary code), generally stipulated in 8. That is: 8 bits equals one byte, but that amount can be altered, so un byte is actually equivalent to even n bits ordered. This unit does not have a conventional symbol of representation, but in some countries the letter `` B '' is used.

The origin of this term is assumed in the acronym in English of Binary Tuple o Tupla binary, which is equivalent to an orderly sequence of binary elements.

However, the phonetic similarity of byte with bite ( bite or bite in English) also meant its use since it was the minimum amount of data that could be fed to a system at a time (the minimum amount that could be bite ).

As for the amount of information that unbytes represents, it is considered that approximately 8 bits are needed to represent a letter in the binary code of most commercial systems of computing today, that is: one byte equals one letter, so an entire paragraph can exceed 100 B, and a very short text will reach the immediately superior unit, the kilobyte (1024 B = 1 kB).

From then on, a whole scale of digital information quantity measurement starts, as follows (according to ISO / IEC 80000-13):

  • 1024 B = 1 kB (one kilobyte, equivalent to a short text)
  • 1024 kB = 1 mB (one megabyte, equivalent to a complete novel)
  • 1024 mB = 1 gB (one gigabyte, equivalent to an entire library shelf full of books)
  • 1024 gB = 1 tB (one terabyte, equivalent to a complete library of small size)
  • 1024 tB = 1 pB (un petabyte, equivalent to the amount of data handled by Google per hour in the world)
  • 1024 pB = 1 eB (one exabyte, equivalent to the weight of all Internet information by the end of the year 2001).

The `` bytes '' and their superior measures are also often used to measure the storage capacity of digital memory devices, or data transfer rates through computer networks of various types.
